[0001] The utility model relates to the technical field of auxiliary balance of rotating bridges, in particular to a load-bearing fulcrum device for auxiliary balance control of rotating bridges. Background Art

[0002] With the continuous development of bridge construction technology, rotating bridges, as a unique bridge structure, have been widely used because they can effectively solve the crossing problems under special terrain and complex traffic conditions. During the construction process, rotating bridges need to be rotated as a whole to achieve accurate docking with the approach bridge or main bridge. In order to ensure the smoothness and safety of the rotation process, load-bearing fulcrum devices are usually used to support and guide the bridge to be rotated.

[0003] In the prior art, the conventional auxiliary balance control load-bearing fulcrum device of the rotary bridge usually adopts the cooperation between the rotary cylinder bracket and the fixed top frame to achieve stable support for both sides of the rotary bridge. At the same time, the rotary tractor is used to guide the rotary bridge to rotate precisely. However, in this process, the transmission guide rollers installed on both sides of the fixed top frame are prone to wear and damage after long-term use, which not only affects the normal operation of the device, but also poses a potential threat to the overall safety of the rotary bridge. In addition, since the structural design of the transmission guide rollers is relatively fixed during installation, the disassembly and replacement process is cumbersome and inconvenient, which brings great challenges to daily repair and maintenance work.

[0004] Therefore, a load-bearing fulcrum device for auxiliary balance control of a rotating bridge is needed to solve the problem that the existing load-bearing fulcrum device has a relatively fixed structure of a transmission guide roller, which is inconvenient for later disassembly and maintenance, thus affecting the use effect of the load-bearing fulcrum device.

A plurality of slots 6 are provided on the left and right sides of the fixed top frame 3. The inner wall of the slot 6 is plugged with a plug-in block 12. A mounting block 4 is installed on the side of the plug-in block 12 away from the fixed top frame 3. Two transmission guide rollers 5 are installed on the inner wall of the mounting block 4, and connecting blocks 11 are installed on the front and rear sides of the plug-in block 12; the connecting block 11 is plugged into the inner wall of the slot 6, and the mounting block 4 is fitted with the fixed top frame 3, so that the mounting block 4 is driven to be installed between the fixed top frame 3 through the fitting between the connecting block 11 and the plug-in block 12 and the slot 6, so as to provide balance for the bridge body 1 to be rotated and increase stability during rotation. The middle transmission guide roller 5 is fitted with the bottom of the bridge body 1 to be rotated, so as to utilize the transmission guide roller 5 to reduce the friction of the bridge body 1 to be rotated during the overall rotation and reduce the energy consumption of the rotating tractor.

[0026] First, the load-bearing fulcrum device body 2 on both sides is lowered by using the rotating cylinder bracket to release the support for the bridge body 1 to be rotated. Then, the mounting block 4 can be pulled upward to drive the plug-in block 12 and the connecting block 11 on one side to slide upward along the inner wall of the slot 6 and disengage. Then, the conveying guide roller 5 can be maintained or replaced. After completion, it will be reset, and the mounting block 4 will be plugged and assembled between the connecting block 11 and the plug-in block 12 and the slot 6. Then, the load-bearing fulcrum device body 2 can be reset and support the bridge body 1 to increase the stability of the bridge body 1 to be rotated during the overall rotation process, thereby improving the use effect of the load-bearing fulcrum device body 2.

[0027] Example 2: On the basis of Example 1, in order to achieve the clamping between the mounting block 4 and the fixed top frame 3, a slide groove 13 is provided on the upper side of the inner side of the plug-in block 12, and a shift block 15 is installed on both sides of the inner wall of the slide groove 13. An elastic member 16 is installed between each two shift blocks 15, and an insertion rod 14 is installed on the side of the shift block 15 away from the elastic member 16. A card slot 7 is provided on both sides of the inner wall of the slot 6; the end of the insertion rod 14 away from the shift block 15 passes through the connecting block 11 and is plugged into the inner wall of the card slot 7, and the elastic member 16 is installed between each two shift blocks 15. The elastic member 16 is arranged on the lower side of the inner wall of the slide groove 13, so that the elastic force of the elastic member 16 is used to facilitate the insertion of the insertion rod 14 into the inner wall of the card slot 7, so as to assemble the mounting block 4 and the fixed top frame 3; the shift block 15 is designed in an "I" shape, and the shift block 15 fits in with the top of the plug-in block 12, so that by shifting the two shift blocks 15 toward each other, the insertion rod 14 on one side is driven to move, and the elastic member 16 is squeezed, thereby contacting the restriction on the mounting block 4, so that it can be removed to maintain the conveying guide roller 5.

[0028] When the cam 14 is in the closed position, the two levers 15 are released, and the lever 14 is released to move in opposite directions along the inner wall of the slot 13, and the lever 14 on one side is driven to disengage from the inner wall of the slot 7, and the elastic member 16 is squeezed at the same time, so that the elastic member 16 is compressed on the inner wall of the slot 13. At this time, the mounting block 4 can be pulled upward and disengaged from the slot 6. Then, the conveying guide roller 5 can be maintained or replaced. After completion, it is reset, and the mounting block 4 is plugged into the slot 6 by the connecting block 11 and the plug-in block 12. At the same time, the two levers 15 are released, so that the elastic force of the elastic member 16 drives the two levers 15 to move in reverse, and at the same time drives the plug-in rod 14 to penetrate the connecting block 11 and insert into the inner wall of the slot 7, thereby clamping the mounting block 4 and the fixed top frame 3.

[0029] Example 3: On the basis of Example 2, in order to realize the vibration caused to the fixed top frame 3 when the bridge body 1 to be rotated rotates, two rubber blocks 9 are installed on the side of the mounting block 4 close to the fixed top frame 3, and a plurality of rubber protrusions 10 are installed on the side of the rubber block 9 close to the fixed top frame 3. A plurality of connecting grooves 8 are provided on the left and right sides of the fixed top frame 3; the rubber block 9 is inserted into the inner wall of the connecting groove 8, and the rubber protrusion 10 fits with the inner wall of the connecting groove 8, and the rubber protrusion 10 is squeezed and pushed to be in an extruded deformation state. Through the cooperation between the rubber block 9 and the rubber protrusion 10, when the bridge body 1 to be rotated rotates as a whole, the influence of the extrusion vibration of the conveying guide roller 5 on the fixed top frame 3 is reduced, thereby improving the service life of the load-bearing fulcrum device body 2.

[0030] When assembled between the mounting block 4 and the fixed top frame 3, the two rubber blocks 9 on one side thereof will be inserted into the inner wall of the connecting groove 8, and at the same time drive multiple rubber protrusions 10 to fit with the inner wall of the connecting groove 8, and make the rubber protrusions 10 be squeezed and pushed into a deformed state. At this time, when the bridge body 1 to be rotated rotates, it drives the conveying guide roller 5 to rotate and generate vibration, so as to utilize the cooperation between the rubber block 9 and the rubber protrusion 10 to slow down and disperse the vibration, thereby slowing down the vibration caused to the fixed top frame 3, so as to improve the service life of the load-bearing fulcrum device body 2, and at the same time improve the stability of the assembly between the mounting block 4 and the fixed top frame 3.

[0031] In actual use, first, the load-bearing fulcrum device body 2 on both sides is lowered by the swivel cylinder bracket to release the support for the bridge body 1 to be rotated. Then, the two shifting blocks 15 can be squeezed to move toward each other along the inner wall of the slide 13, and the insertion rod 14 on one side thereof is driven to disengage from the inner wall of the card slot 7. At the same time, the elastic member 16 is squeezed to make the elastic member 16 compressed on the inner wall of the slide 13. At this time, the mounting block 4 can be pulled upward to drive the plug-in block 12 and the connecting block 11 on one side thereof to slide upward and disengage along the inner wall of the slot 6. Then, the conveying guide roller 5 can be maintained or replaced. , after completion, reset it, and use the connecting block 11 and the plug-in block 12 to plug and assemble the mounting block 4 with the slot 6. At the same time, loosen the two shifting blocks 15, so that the elastic force of the elastic member 16 drives the two shifting blocks 15 to move backwards, and at the same time drives the insertion rod 14 to penetrate the connecting block 11 and insert into the inner wall of the card slot 7, thereby clamping the mounting block 4 and the fixed top frame 3. Then, the load-bearing fulcrum device body 2 can be reset and support the bridge body 1 to be rotated, thereby increasing the stability of the bridge body 1 to be rotated during the overall rotation process, thereby improving the use effect of the load-bearing fulcrum device body 2;

[0032] When assembled between the mounting block 4 and the fixed top frame 3, the two rubber blocks 9 on one side thereof will be inserted into the inner wall of the connecting groove 8, and at the same time drive multiple rubber protrusions 10 to fit with the inner wall of the connecting groove 8, and make the rubber protrusions 10 be squeezed and pushed into a deformed state. At this time, when the bridge body 1 to be rotated rotates, it drives the conveying guide roller 5 to rotate and generate vibration, so as to utilize the cooperation between the rubber block 9 and the rubber protrusion 10 to slow down and disperse the vibration, thereby slowing down the vibration caused to the fixed top frame 3, so as to improve the service life of the load-bearing fulcrum device body 2, and at the same time improve the stability of the assembly between the mounting block 4 and the fixed top frame 3.
